Creating representative graphs

[Nick]

Is it possible to 'draw' certain curves in a chart? I want to place a few normal distribution or sigma curves to make a point - so far the best I can find is to make a datatable and edit the curves to make them look right.
Thanks, Nick

You can use the curve tool or any of the other drawing tools to draw *atop* a
chart you've already created. Once done, it's a good idea to group the drawing
and the chart so they don't get moved apart accidentally.
